Design and Research on Fatigue Test System for Anti Pinch Device of Railway Locomotive Doors
Aiming at the problem of lack of automated testing equipment and low data acquisition accuracy in fatigue testing of anti pinch devices for railway locomotive doors,a fatigue testing system and its usage method that can replace manual labor are proposed.Two fatigue testing methods,counting mode and failure mode,are designed,which can directly and automatically complete the opening and closing test of the anti pinch device.It can simulate the process of a person accelerating to close the door,receiving damping force,then closing the door at a constant speed,and then opening the door again during the process of closing the door.Accurate data statis-tics of the anti pinch device switch test process are beneficial for product performance analysis and improvement optimization design,and improve the design and maintenance efficiency of locomotive door anti pinch devices.At the same time,it can provide reference and inspiration for the design of fatigue testing systems for other similar products.
